This triggered a long-standing bugbear of mine: why are we
using these variable-length encodings at all? Does anybody
really care about UTF-8 being "self-synchronizing," ie does
anybody actually use that in this day and age? Sure, it's
backwards-compatible with ASCII and the vast majority of usage
is probably just ASCII, but that means the other languages
don't matter anyway. Not to mention taking the valuable 8-bit
real estate for English and dumping the longer encodings on
everyone else.
The German ß becomes SS when capitalised. It's no encoding issue.
